Abstract

A model for H2O, CH4, H2 and odd hydrogen is developed that properly relates the measured mixing ratios in the stratosphere to escape of H in the form of Jeans flux, charge exchange and polar wind. The resulting model predicts a temperature-dependent jeans flux in agreement with recent measurements.
